Mineralogical and geochemical compositions of the coal in the Guanbanwusu Mine, Inner Mongolia, China: Further evidence for the existence of an Al (Ga and REE) ore deposit in the Jungar Coalfield

Aluminum-hydroxide (boehmite and diaspore)-, Ga-, REY (rare earth elements and Y)-, and Al-rich Pennsylvanian Taiyuan Formation coals have previously been found in the Jungar and Daqingshan Coalfields, Inner Mongolia, China. Gallium, REY, and Al are potentially extractable and usable elements in combustion residues derived from these coals. This paper reports new results on 50 bench samples of the No. 6 coal from the Guanbanwusu Mine, Jungar...
